Red Pepper Tomato Sauce Cooking Guide

Step 1: Sauté the Onion
Begin by heating the extra-virgin olive oil in a large skillet over medium heat. Once the oil is shimmering, add the finely chopped onion. Sauté for about 5 minutes, or until the onions are translucent and fragrant.
Step 2: Add the Red Bell Peppers
Next, add the thinly sliced red bell peppers to the skillet. Cook for about 10-12 minutes, stirring occasionally, until the peppers have softened and started to caramelize. This step is crucial as it brings out the natural sweetness of the peppers.
Step 3: Incorporate the Tomatoes
Once the peppers are tender, add the peeled, seeded, and finely chopped tomatoes. Stir well and allow the mixture to simmer for another 5-7 minutes. The tomatoes will break down and meld with the peppers, creating a beautiful sauce.
Step 4: Spice it Up
Now it’s time to add the chopped chipotle chile in adobo sauce. Stir it into the mixture and let it cook for an additional 3-4 minutes. Adjust the amount of chipotle to your desired spice level—add a whole one for an extra kick!
Step 5: Season and Add Basil
Remove the skillet from heat and stir in the coarsely chopped basil. Season the sauce with salt and freshly ground black pepper to taste. The fresh basil will bring a refreshing note to the sauce.
Step 6: Blend if Desired
If you prefer a smoother sauce, you can use a blender or food processor at this stage. Blend until you reach your desired consistency. For a chunkier texture, leave it as is!
How to Make It Lighter

- Reduce the amount of olive oil to 1 tablespoon for a lighter sauce.
- Use fresh tomatoes exclusively instead of canned ones to cut down on sodium.
- Incorporate more vegetables like zucchini or carrots to bulk up the sauce without adding extra calories.
- Serve over zucchini noodles or whole grain pasta to keep the dish light and nutritious.
Mistakes Even Pros Make
- Overcooking the onions can lead to bitterness—aim for a golden color rather than deep brown.
- Skipping the peeling and seeding of tomatoes can result in a watery sauce.
- Not adjusting the seasoning at the end can leave the sauce tasting flat.
- Forgetting to chop the chipotle finely can lead to unexpected spicy bites.
Freezer-Friendly Notes
One of the best things about this Red Pepper Tomato Sauce is its freezer-friendly nature. Allow the sauce to cool completely before transferring it to airtight containers or freezer bags. It can be stored in the freezer for up to 3 months. When ready to use, simply thaw in the refrigerator overnight or reheat directly from frozen on the stovetop over low heat, stirring frequently.
